What grease filter exchange looks like in Aldershot
There are about 80 restaurants, cafés and works canteens and about 33 takeaways in Aldershot and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Fire safety in Aldershot falls to Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Rushmoor council that sends environmental health officers to food businesses in Aldershot. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Commuter trade near Aldershot station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Fleet Community Hospital is the nearest hospital to Aldershot, about 4.7 miles north-west. Church and community hall kitchens, near Church of the Holy Trinity or anywhere around Aldershot, are easy to forget, but their extracts collect grease like any other.

Grease filter exchange in Aldershot, done properly
Each visit is quick and tidy. The greasy filters come out, clean ones go in, and we check they’re seated with no gaps. If something looks wrong, we tell you. Common call-outs are for filters that come out of the sink still dirty and damaged filters letting grease past, across wall canopies, restaurants and pubs and island canopies.
Most kitchens in a town like Aldershot can’t close for a day, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Never cook with the extract switched off
- Let us know if your cooking hours increase
- Report damaged filters so they can be replaced
- Make sure no filter is left out
Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
Your questions about grease filter exchange in Aldershot
Who would carry out a food hygiene inspection at a kitchen in Aldershot?
Food hygiene inspections in Aldershot are carried out by Rushmoor council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can a school canteen extract in Aldershot be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 25 schools and colleges with food registrations within roughly a mile and a half of Aldershot. You can phone us on 0345 646 2711 or use the quote form with the dates the site is empty.
What paperwork should we keep on file?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them where they can be found quickly.
How long does the visit take?
That depends on how much there is to do, but for a typical site it takes well under an hour for most canopies. We’ll confirm it with the quote.
Will you tell us when the next visit is due?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
What does grease filter exchange cost?
The cost depends on your filters and the schedule. Just ring 0345 646 2711 or drop us a line for a fixed quote once we know your canopies.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Can we skip TR19 cleans if the filters are changed regularly?
No. Filter exchange works between full cleans, not instead of them. TR19® cleaning covers the canopy, plenum, ductwork and fan and comes with a certificate and photo report.
The process
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and leave you the report. The visit itself takes a short visit, depending on how many filters the canopies hold. The more we can see of the system beforehand, the smoother the visit to Aldershot will be.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend
- Tell us where we can park and unload

Related advice
For landlords and multi-site operators
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
We also work for facilities teams across offices, schools and healthcare across Hampshire. Larger estates can be phased building by building to keep disruption down.
How we price grease filter exchange
Every site gets its own quote. This is what makes a difference:
- Whether it’s a one-off visit or part of a schedule
- Site rules, permits and inductions
- The condition of the system
- The times the site is available
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
Helping us quote
We can often survey from photos. Try to include:
- The site address and the type of premises
- The times we could work without disrupting the site
- A few general shots of the system
- Problems your staff have spotted
For a fixed quote, give us a ring on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
Part by part
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
Canopy filter housings
Filters sit in a housing or channel in the canopy. If it’s bent or greasy, filters won’t seat properly.
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
What happens if it’s left?
Grease-loaded filters are a fire risk in their own right. A flare-up on the range can reach them and grease in the duct can carry a fire further. Clean filters mean less fuel in the canopy. A fresh certificate on file is the best thing to have when someone asks to see your records.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.
